Catalogue description

Dealer description — Oliver & Clarke

Watches still played a critical role in military service in the 1970s. As a result of the need for a more robust dive watch tailored to the military's needs, the United States Department of Defense issued the MIL-W-50717 standard, which put forth a more robust list of required specifications, more so than any prior contract. There were many options for lower level officers and platoons when it came to timepieces, but for the best of the best including the renowned Navy Seals, the Benrus Type I and Type II were the best option. Benrus made these pieces exclusively for the military between 1972 to 1980, with this particular example dating to circa 1976 ( November of 1976 to be exact ). The 42.5mm asymmetrical case remains unpolished and retains its original 'sandblasted' finishing and shows normal signs of wear. Flip it over, and the engravings on the caseback denoting it's military provenance and year of manufacture are crisp and clear. The screw-down crown and bi-directional rotating bezel also features the characteristic ' sandblasted' matte finishing that matches that of the case. Inside, the matte black 'sterile' dial with white printed indices is very nicely preserved, with excellent white printing, evenly patinated Tritium plots, and a matching white-painted handset. Unlike nearly all other Type Is and Type IIs with a black acrylic 12-hr insert, this piece features an exceedingly rare blue acrylic insert, believed to be a prototype with only a handful in circulation. Due to their limited production, active use during military trials, decommissioning, and flat out loss, not all that many of these pieces survive today — particularly in this kind of condition. We are pleased to offer this Type II up for its next tour of duty, and invite you to strap a real piece of history to your wrist.

Historical context

Quartz Revolution (1969 – 1990)

Seiko's Astron begins mass quartz timekeeping; traditional industries contract sharply.

Quartz and digital watches transformed the market after 1969. Swiss employment collapsed, Japanese and Hong Kong production soared, and the Swatch (1983) helped the Swiss industry recover; mechanical watches survived as luxury goods.

Atlas type guide

Military, pilot and travel watches

The wristwatch owes much of its adoption by men to warfare and aviation. Wristlets — small pocket watches soldered with lugs and worn on a strap — were used in colonial campaigns and became standard equipment in the First World War, with protective grilles over the crystal ('shrapnel guards'). Louis Cartier's Santos (1904), designed for the aviator Alberto Santos-Dumont, is often cited as an early purpose-made pilot's watch.

In the Second World War governments specified watches in detail: the German B-Uhr observation watches, the American A-11, and the British 'W.W.W.' (the 'Dirty Dozen' set of 1945). After the war, jet travel brought GMT and world-time watches, which show two or more time zones at once — Louis Cottier's world-time mechanism and the Rolex GMT-Master (1955) are examples.

What to look for

  • Military markings on the case back: broad arrow, issue numbers, 'W.W.W.', 'A.T.P.'
  • High-legibility black dials with luminous Arabic numerals; oversized crowns for gloved hands.
  • 24-hour hands and rotating 24-hour bezels or city rings on GMT/world-time watches.
  • Wire lugs on early wristlets converted from pocket watches.

Dating clues

  • Wire-lug wristlets: c. 1900–1925.
  • Military specifications of the Second World War: 1939–1945.
  • GMT and world-time wristwatches: mainly after 1950.
